FWIW, it's not a starter set, it's a playtest. It's stress testing things, and leaning on Pathfinder assets. You're not missing out on the full meal deal right now.
I feel like that actually makes it worse. Making people pay to be playtesters? Last I knew playtesting was a job.
I haven't really looked into it at all because I'm not interested, but do they at least state that you'll get the updated material that you paid for when it releases?
